April 28, 2009--Hot dust and young stars in the galaxy known as M33 sparkle with color in this combination of images from two NASA probes: the Galaxy Evolution Explorer (GALEX) and the Spitzer Space Telescope.

The image was released to mark the sixth anniversary of GALEX, an ultraviolet telescope that studies galaxies beyond the Milky Way. At roughly 2.9 million light-years away, M33 is actually one of the closest galaxies to our cosmic home.
